Roxanne Rubin, a registered Republican from Henderson, Nev., was arrested Fridayon a felony charge of attempting to vote twice in the same election.

FBI agents took Rubin into custody as she arrived for work at the Riviera hotel-casino, according to the Associated Press. Rubin had roused suspicion on Oct. 29, after casting a vote at her precinct in Henderson, and then allegedly attempting to vote at a different polling site in Las Vegas later that day. Election workers at the second location ran her name through a database, which showed that she had already voted. When confronted by officials, Rubin reportedly claimed that their database was incorrect, and that she had not yet voted. She was ultimately prevented from casting the second vote.

A complaint was subsequently filed with Nevada's Elections Integrity Task Force, which carried out the investigation.
